The effects of quenching water temperature（20 ~ 80 ℃） on the microstructure and mechanical property of 2219 Al alloy forging ring were studied by room temperature tensile test, optical microscope（OM），scanning electron microscopy（SEM） and transmission electron microscopy（TEM）. The results showed that the tensile strength and yield strength first increased and then decreased with the increase of quenching temperature. The elongation anisotropy index of 2219 Al alloy ring forging was significantly increased when the quenching water temperature exceeds 60 ℃ due to the formation of coarse grain boundary precipitates. The high strength and elongation of 2219 Al alloy ring forging was obtained under the quenching water temperature at 40 ℃. The axial tensile strength, yield strength and elongation were 418 MPa，300 MPa and 9.3%, respectively. The radial tensile strength，yield strength and elongation were 420 MPa，300 MPa and 9.8%, respectively. The tangential tensile strength，yield strength and elongation were 447 MPa，329 MPa and 12.6%，respectively.
